【Abstract】 The knowledge management mechanism of the Mineral Processing Expert System Environment (MPESE) is expressed. Object knowledge representation methods of MPESE is designed. The combination of rule and frame expresses knowledge hierarchies. Computation model adopts frame and model integrated representation method. Uncertain knowledge is represented by improved Bayes method and certainty factor theory. Knowledge acquisition mainly includes manual acquisition and automatic knowledge learning.更多还原
